LUNCH-BOX.

Specification of Letters Patent.

Patented Mar. 22, 1910.

Application filed December 9, 1909. Serial No. 532,183.

T o ad whom 'it may concern.'

Be it known that I, CHARLES KUKURUDA, a subject of the King of Hungary,residing at Flint, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Lunch-Boxes, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to lunch boxes, and the objects of my inventionare; first, to provide a collapsible box that can be easily carried inthe pocket when collapsed or folded; second, to furnish a collapsiblelunch box with means for retaining the same in a set up or collapsedposition, third, to provide a lunch box consisting of comparatively fewparts easily and quickly collapsed or folded; and fourth, to accomplishthe above results by a lunch box that is simple in construction, durableand highly efficient as a receptacle for lunch and other matter'.

I attain the above objects by a structure that will be hereinafterdescribed in detail and then claimed, and reference will now be had tothe drawings forming a part of this specification, wherein there isillustrated a preferred embodiment of the invention, but

' it is to be understood that the structural elements thereof can bevaried or changed, as to the size, shape and manner or assemblagewithout departing from the spirit of the 1nvention.

In the drawings F igure 1 1s a perspective view of a lunch boxconstructed in accordance with my invention, showing the saine in a setup and closed position, Fig. 2 is a bottom plan of the lid detached,showing the manner of folding one of the side flanges of the lid, Fig. 3is an enlarged cross sectional view of a portion of the lid, Fig. 4 isan end view of the box with the lid thereof removed, Fig. 5 is a sideelevation of the same, Fig. 6 is a plan of the box folded or collapsed,Fig. 7 is an end View of the same with the lid in position, and Fig. 8is a perspective view of the body of the box showing the manner ofcollapsing or folding the same.

The box or receptacle can be constructed of various kinds of material,but it is preferable to use pieces of cardboard or light metal platesand to cover the same with a fabric that will retain the pieces ofcardboard in position, whereby the box can be collapsed into a smallparcel. While there is shown a box having the walls thereof made ofcardboard and fabric, it is to be under'- stood that the entirestructure can be made of canvas or a suitable material.

The box comprises a bottom 1, side walls 2 and 3, end walls 4 and 5 anda lid 6. The lid 6 is provided with depending foldable flanges 7 and 8,the latter being provided with tabs 9 having button holes 10 adapted toreceive buttons 11 carried by the walls 2 and 3 intermediate the endsthereof.

rIhe end walls 4 and 5 are provided with straps 12 and extending underthe bottom l of the box and upwardly through the straps 12 is a strap 13having one end thereof provided with a buckle 14, whereby thc ends ofthe strap'13 can be connected to retain the lid 6 upon the box, eitherin a set up or collapsed position.

The lid 6 as shown in Figs. 2 and 3 of the drawings comprises a backingor plate 15 having both sides covered by fabric 16 and the fabric uponthe sides of the backing has the edges thereof connected together, as at17. The fabric is continued to form a case 18 having a backing or plate19 adapted to constitute one of the depending flanges 7 or 8. The case18 is not necessarily made integral with the fabric 16, as it can bemade separately and connected to the fabric 16, as at 17. It is theconnection at 17 that permits of the flanges 7 and 8 being folded overupon the lid 6. The backing 19 forming the flanges 8 is cut away at theends thereof, whereby the flanges 7 can be folded over upon the fianges8, as at 20. lVhen the fianges of the lid are folded, the tabs 9 areadapted to extend inwardly upon the lid.

The end walls 4 and 5 of the box 1 are composed of a plurality of piecesof backing 21 held in place by fabric upon both sides of the pieces ofbacking, the fabric being connected as indicated by dot and dash lines22, shown in Fig. 4, and it is upon these dot and dash lines that theend walls are collapsed. It will be noted by the dotted lines in Fig. 4that some of the pieces 21 are triangular while others are substantiallytriangular.

The side walls 2 and 3 are each made of two pieces of backing 23 coveredby fabric, the fabric being stitched or connected as indicated by thedot and dash lines 24, whereby the walls 2 and 3 can be folded.

CIT

The inanner of folding the boX is best shown in Fig. 8, where it will beobserved that the end walls fold upon six converging lines, whereby partof each end wall will fold upon itself while another part will fold uponthe upper edges of the side walls 2 and 3. For instance, the triangularsection A folds inwardly upon the bottoni l, the sections l folddowmvardly upon the section A, this inovelnent of the sections B causingthe upper sections C of the side walls 2 and 3 to fold upon the lowersections l), while the sections ll fold upon the sections C with thesection F upon the Sections E. After the body of the box has beenfolded, the lid is placed therein and the ends of the strap 13connected.

The backing used in between the fabric adds rigidity to the box when ina set up position wit-hout inaterially increasilig the weight or cost ofthe saine.

Having now described iny invention what I claini as new, is

A collapsible lunch box, comprising a body portion and a lid, said lidprovided with side and end flanges, said side flanges havingangularfolds whereby the end flanges can be folded upon the side flanges, saidbody portion including a bottoni, side and end walls, each of said sidewalls consisting of a pair of longitudinal folds whereby each of theside walls can be folded upon itself, and each of said end walls havinghorizontal and angular folds whereby each of said end walls can befolded upon itself and the side walls folded upon the end walls.
